My brother-in-law gave me a 20 ft trailer house frame in exchange for me rebuilding the slop gate in his manure spreader. I have been debating on how to build it. My first thought was to just sheet the deck and add lights. Then I got to thinking that it would be nice to have it enclosed but I have a welding shop and it is kinda a pain to load steel into enclosed trailers. So now I am thinking of either an awesome snowmobile trailer style flatbed and ad cabinets and an aluminum skirt, or should I figure out some type of soft sided enclosed where the sides will slide. Which of these would you all find more useful and versatile?

installed the side door today. i have to weld the door latch together tomorrow using black pipe and galvanized pieces how much of the galvanization should i grind off? What would you use? Mig or arc welder and a fan blowin the zinc oxide away. I really dont want to get sick! I have never welded galvanized parts.
